SILVANUS I-IUSSEY, OF BRANT, NEW YORK.

WRENCH.

SPECIFICATION forming part of Letters Patent N0.4'75,450, dated May 24, 1892.

Application filed September 14, 1891. Serial No. 405,578. (No model.)

To a/ZZ whom it may concern.'

Be itknown that I, SILVANUs HUssEY, a citizen of the United States, residing at Brant, in the county of Erie and State of New York, have invented a new and useful Improvement in Wrenches, of which the following isa specication.

This invention relates to an improvement in the wrench shown and described in Let-- ters Patent of the United States No. 444,937, granted to me January 20, 1891.

The object of my present improvement is tosimplify the construction of the wrench and reduce its cost of manufacture.

In the accompanying drawings, Figure l is a side elevation of the wrench. Fig. 2 is a sectional elevation thereof at right angles to Fig. l. Fig. 3 is a longitudinal section of the head ofthe wrench in line o: Fig. 2. Fig. 4 is a cross-section' thereof in line y y, Fig. l.

Like letters of reference refer to like parts in the several figures.

A represents the handle of the Wrench, which is preferably constructed of metal and slotted lengthwise to reduce its weight.

B is a stationary jaw arranged at theinner end of the handle, and C is a rectangular loop or socket formed in the inner portion of the handlein a plane parallel therewith, as shown in Fig. 2. i

D is a movable jaw, larranged opposite the stationary jaw B' and having a rectangular shank D', which slides in the loop C of the The movable jaw D is preferably provided with two laterally-projecting jaws E E', each having an angular or V- shaped face, and the iixed jaw B is preferably provided with two laterally-projecting sockets or recesses F F. In the socket or recess F is arranged a movable gripping bar or jaw f, having a serrated face, which may be used in conjunction with the laterally-projecting jaw E for gripping pipes or round bars. The socket F is preferably provided with a similarlyshaped jaw or bar f', having a pointed or cutting edge, which may be used in conjunction with the laterally-projecting jaw E for cutting pipes or round bars.

G represents the rotary screw for adjusting the movable jaw toward and from the fixed jaw. This adj usting-screw is attached to the movable jaw in such manner thatit is free to turn therein; but is held against moving lengthwise thereon. In the construction represented in the drawings the unthreaded upper portion of the screw is arranged in an opening formed in the movable jaw, and is held against lengthwise movement therein by a collar or shoulder g, formed on the screw and bearing against the inner side of the movable jaw, and a nut g', applied to the threaded end of the screw and bearing against a shoulder formed by reducing said threaded end, as shown in Fig. 2. The threaded portion of the adj usting-screw engages in a threaded longitudinal opening h, formed Apartly in the fixed jaw B and partly in a boss or enlargement H, arranged at the inner portion of the handle on the front side thereof. The lower portion of the adj usting-screw is angular or flat-sided and guided in a longitudinal socket or sleeve I, having a bore of corresponding shape, and which turns in an opening or bearing arranged in the cross-bar 7c, connecting the outer ends of the members of the slotted handle. This socket projects beyond the end of the handle and is prevented from moving lengthwise 1n its bearing by an annular shoulder l, formed on the socket and bearing against the inner side of the cross-bar lo, and a screw-nut Z', applied to the screw-threaded outer end of the socket and bearing against the outer face of the cross-bar Zt. This screw-nut also serves as a thumb-piece for turning the socket. The lower portion of the slot in the handle is enlarged to receive the socket I, as shown. Upon turning the socket I in either direction by means of its thumb-piece the adjustingscrew is caused to turn in the threaded opening in the handle and move inward or outward on the latter, thereby causing the movable jaw carried by the screw to move toward or from the stationary jaw and varying the space between the jaws. The adjustingscrew is compelled to turn with the rotary socket I, and is at the same time capable of sliding longitudinallyin the same, thus forming a sliding connection between the adjusting-screw and the socket, which permits of a compound rotary and lengthwise movement of the screw.

In assembling the parts of the wrench the IOO socket I is first placed in its bearing and theadjusting-screwis attached to the movable jaw. The adjusting-screw is then screwed into the threaded opening of the handle and its angular end fitted into the rotary socket I, and the shank of the movable jawis at the same time guided into the loop or socket C of the handle.

By making the outer jaw movable and arranging-its shank to slide in the socket formed in the upper portion of the handle the rivetholes and rivets required for securing the shank of the stationary jaw to the handle in the patented Wrench before referred to are dispensed with, thus lcssening the amount of labor involved in the construction and assemblage of the parts of the wrench and reducing its cost of production.

I claim fas my invention- 1. The combination, with the handle and a fixed jaw arranged at the inner end thereof, of a socket formed in the handle in a plane parallel therewith, ay movable jaw havin-g a shank guided in the socket of the handle, and an adjusting-screw carrying the movable jaw and arranged in a threaded opening formed in the inner portion of the handle, substantially as set forth.

2. The combination, with the handle having ryin g the movable jaw, engaging in a threaded opening in the inner portion of the handle and connected with said rotary socket, sub

1 stantially as set forth.

3. The combination, with the handle having a fixed jaw at its inner end and a socket or loop arranged in a plane parallel with the handle, of a movable jaw having a shank guided in said socket or loop, a sleeve journaled in the outer portion ot' the handle and having an angular bore, and a rotary adjusting-screw carrying the movable jaw, engaging in a threaded opening inthe inner portion of the handle and having an angular portion which slides lengthwise in the bore of said sleeve, substantially as set forth.

Witness my hand this 3d day of August, 1891.
